This is my brother-in-law's laptop for school. Intel i5-8250U 8GB RAM 1TB spinner disk CPU very low- 0-10% Memory steady at about 4GB But the HDD is always at 100%, with nothing running, making it really slow. Virtually brand new. Scrubbed of all Dell factory bloatware performed Nothing special in startup programs Very clean- normally a machine like this runs just fine. Ive disabled Windows search, doesnt help. Disabled Windows MSE. Performed all Windows updates, restarted multiple times. Malwarebytes, SuperAntiSpyware and Spybot scans Rolled back Adobe Flash updates Set to high performance mode Disabled the superfetch service Set virtual memory to1.5gb min, 12gb max What other things can I do, besides flatten it and install a (long overdue) SSD?
